Commercial Roof Gutter & Waterproofing Upgrade

CT Building Maintenance completed a commercial roof rectification, replacing a failing box gutter and parapet wall flashings and improving drainage to stop water getting into the building.

Project scope

• Box gutter: Approx. 10 lineal metres of existing guttering and parapet flashings removed and replaced with a new box gutter along the full side of the building
• Flashings: New parapet wall flashings plus a new corner flashing above a window
• Drainage: Upper roof downpipe extended towards the drop box on the western side
• Materials: Mechanical fixings and commercial-grade sealants

What we did

1. Access: Carefully cut back a small section of the existing roofing membrane to reach the box gutter.
2. Removal: Removed and disposed of approximately 10 lineal metres of existing guttering and parapet wall flashings.
3. New box gutter and flashings: Supplied and installed a new box gutter and parapet wall flashings, using mechanical fixings and commercial-grade sealants where required.
4. Water ingress point: Installed a new corner flashing above the window to address an identified leak.
5. Drainage: Extended the upper roof downpipe towards the drop box to improve stormwater discharge.

The result

A solid preventative maintenance and waterproofing upgrade that protects the building from further water ingress and improves the long-term performance of the roof drainage system.
